How can aluminum windows and doors be insulated through the hot summer

-

Generally speaking, the factor that affects windows and doors heat insulation basically has two points: heat radiation and heat conduction. The sunshine time is longer in summer, the sunlight penetrates the glass directly in the room. One part of the thermal radiation can be absorbed or reflected by the glass, the other part is released through the glass in the room and increase the indoor temperature constantly. It is very important to do a good shading for aluminum windows and doors . 1.Shading with curtains Choose the curtain of shading fabric, match again with shading cloth, also can have very good shading effect. But the disadvantage is indoor if longtime no have sunshine will be harmful to human health. 2.Using glass insulation film Glass insulation film is a kind of film that sticks on glass surface, this is a economical and practical method. The disadvantage is that the film use time is limited, after long time of using, maybe appear some bubbling, and rolling at ...

Introduction about 40G QSFP+ SR4 BIDI modules

-
图片
With the development of the networks, upgrading the 10G to 40G networks is the requirement of networks, But there is a very largest problem to build the cable system when upgrading, especially the short distance transmission of 40G. So in order to solve this problem, 40G QSFP+ SR4 BIDI modules produced by engineers… And today, we will introduce this to you , and hope it can be helpful for you! 1. What is 40G QSFP+ SR4 BIDI ? 40G QSFP+ SR4 BIDI is different from the other 40G QSFP+ modules: Other 40G QSFP+ modules (such as QSFP+ SR4 / LR4) use 8 channels to realize 40G transmission, But the 40G QSFP+ SR4 BIDI just use 2pcs 20G channel to reach this function, every channel can transmit and receive the signal from one multimode cable, But also need notice that 40G QSFP+ SR4 BIDI must be used by pairs. 2. How does it work? To realize the 40G QSFP+ SR4 BIDI transmit the signal, need three steps: Step1: Combining four electrical signal to 2pcs 20G el...
